Fair enough :) In any case, the original problem is solved. Thanks for the help!
Actually, I found this post while looking for a solution: https://github.com/bUnit-dev/bUnit/discussions/305 Removing the SetupModule from the Testbase and replacing it with
testContext.JSInterop.Mode = JSRuntimeMode.Loose;
did the trick. I can work with this for now. Though, if you have any concerns with this approach, I would be open to hear them. I gotta admit that I don't fully understand what is going on here.
Hi,
while this worked to resolve the dependency, I encountered the following error when adding a form with a TextObject
Bunit.JSRuntimeUnhandledInvocationException: bUnit's JSInterop has not been configured to handle the call:
Bunit.JSRuntimeUnhandledInvocationException
bUnit's JSInterop has not been configured to handle the call:
InvokeVoidAsync("initialize", Microsoft.AspNetCore.Components.ElementReference, "0HN55GR2KUKHU", null, null)
Configure bUnit's JSInterop to handle the call with following:
SetupVoid("initialize", Microsoft.AspNetCore.Components.ElementReference, "0HN55GR2KUKHU", null, null)
or the following, to match any arguments:
SetupVoid("initialize", _ => true)
The setup methods are available on an instance of the BunitJSInterop or
BunitJSModuleInterop type. The standard BunitJSInterop is available
through the TestContext.JSInterop property, and a BunitJSModuleInterop
instance is returned from calling SetupModule on a BunitJSInterop instance.

I fear that this error is thrown because he cannot resolve a dynamically created javascript file. This, of course would make testing difficult while working with Blazorize. Do you have an idea on how to work around this or is this a bUnit issue?
Edit: I pushed the new changes into the repo
hi
Can you fork this sample and add your code to reproduce the error?
Thanks

Hi,
I added my code. It shows the same error as in my project https://github.com/PDarioJer/abp-samples

I kept the Testbase the same as in the blogpost. As you can see, I kept very close to the Tutorial from the ABP documentation, so someone else could encounter the same problem. Do I maybe have a missing dependency here?
Once I updated the nuGet packages to the new ABP version, my integration tests throw the following error. As you can see, I used the SampleTests as an example:

FlagIconproperty in this version, please see the migration guide. You should probably have an old NuGet package version somewhere in your test application, or in one of the dependent projects. Please check package versions manually. If you could not find the reason, feel free to open a new ticket and after that share your project with us, so we can better assist you.
Thank you. Apparently updating the packages via ABP Suite fixed the versioning problem.

Thank you, this helped!
Unfortunately, the GuidGenerator is a protected property, so I won't be able to set it manually. Getting the ItemManager through DI is an option, however, I don't want it to use the actual ItemRepository but a Substitute, so I can return a fake return value on the FindByItemNrAndVariantAsync(...) method.
My question here is: Is there a way to provide the domain service with an implementation of the GuidGenerator without using the IDomainService interface? Or alternatively, is there a way to get the ItemManager through dependency injection but with a mocked ItemRepository?
When I call GuidGenerator.Create() in my DomainService, that I instantiated in a test, I get a NullReferenceException. I think I could solve this by implementing the IDomainService instead and then mock the IGuidGenerator interface. However, there really is no need to do that here aside from testing concerns.
Do you have any suggestions on how to workaround this issue?
(ItemManager.cs)
using System.Collections.Generic;
using System.Threading.Tasks;
using Volo.Abp.Domain.Services;
namespace TestPlatform.Items;
public class ItemManager : DomainService
{
private readonly IItemRepository _itemRepository;
public ItemManager(IItemRepository itemRepository)
{
_itemRepository = itemRepository;
}
public async Task<Item> CreateAsync(
string itemNr,
int variantCode,
string description,
)
{
var existingItem = await _itemRepository.FindByItemNrAndVariantAsync(itemNr, variantCode);
if (existingItem != null)
{
throw new ItemAlreadyExistsException(itemNr, variantCode);
}
var newGuid = GuidGenerator.Create();
return new Item(
newGuid,
itemNr,
variantCode,
description,
);
}
}
(ItemManagerTest.cs)
using System.Threading.Tasks;
using TestPlatform.Items.Shared;
using NSubstitute;
using NSubstitute.ReturnsExtensions;
using Shouldly;
using Xunit;
namespace TestPlatform.Items;
public class ItemManager_CreateAsyncShould
{
private IItemRepository itemRepository = Substitute.For<IItemRepository>();
[Fact]
public async Task Return_Item_If_No_Item_With_Same_ItemNr_Exists()
{
itemRepository.FindByItemNrAndVariantAsync(
ValidItemData.ItemNr,
ValidItemData.VariantCode
).ReturnsNull();
var itemManager = new ItemManager(itemRepository);
var item = await itemManager.CreateAsync(
ValidItemData.ItemNr,
ValidItemData.VariantCode,
ValidItemData.Description,
);
item.ShouldBeOfType<Item>();
item.ShouldNotBeNull();
}
}
